Computer reboots in the middle of the night

[span123]

This problem only started 3 nights ago. I shut down the PC at night but when i get up in the morning it has turned itself back on. Any ideas? Thanks in advance

Sure it's not just shutting down to hibernate mine was doing that and would then randomly turn itself on

yep,go into power management to disable hibernate.

Wake on LAN may be enabled, if your PC is starting up and not from hibernating then your PC has Wake from LAN enabled

thanks for the replys the computer is now sorted. The problem was the motherboard, the computer was completely dead a few days ago. New motherboard fitted and it's like a rolls royce.
